摘要

The telescopic ball screw drive has rotary elements, which form a unit and are responsible for retracting- and expanding function. The unit is driven by a drive unit, i.e. moved in rotation, in order to execute the retracting- and expanding function. The unit is mounted in an assembly part, which is linearly guided in a base element and is blocked against rotation.
